Journal ArticleDOI
Hybrid computer vision system for drivers' eye recognition and fatigue monitoring
TL;DR: A hybrid visual system for monitoring driver's states of fatigue, sleepiness and inattention based on driver's eye recognition based on the higher order singular value decomposition of the tensors of real eye prototypes, specific to the visible and NIR spectra.
Journal ArticleDOI
Microwave-based sensors with phthalocyanine films for acetone, ethanol and methanol detection
TL;DR: In this paper, the authors used comb copolymer phthalocyanine (Pc) thin films as sensitive layers for microwave gas sensors at room temperature under exposure to various volatile organic compounds.
Journal ArticleDOI
Broadband Integrated $8 \times 8$ Butler Matrix Utilizing Quadrature Couplers and Schiffman Phase Shifters for Multibeam Antennas With Broadside Beam
TL;DR: In this article, a planar realization of a broadband $8 \times 8$ Butler matrix with phase progressions 0°, ±45° and ±90° has been proposed.
Journal ArticleDOI
Microstrip Antenna Arrays Fed by a Series-Parallel Slot-Coupled Feeding Network
TL;DR: In this article, a slot coupler was proposed for a microstrip antenna array composed of series-fed linear subarrays, in which two microstrip lines are coupled through a slot in a common ground plane.
Journal ArticleDOI
Broadband Rat-Race Couplers With Coupled-Line Section and Impedance Transformers
TL;DR: In this article, a broadband rat-race coupler utilizing a shorted coupled-line section and two shorted quarter-wave long transmission lines has been modified allowing for achieving ideal isolations between two pairs of respective ports.
